on a 3plug ecu
pin 2 wire M1620 on the speed sensor is ground
it is linked to the MAF pin 3 wire 1410
its also linked to pin1 wire M1150 on the glowplug relay
its also linked to the ecu two pins L4/M4 wire M1320/M1320
there is no earth connection other than through the ecu
i would check the ecu earth and also the plugs and pins on the ecu for corrosion
